JOHN S. BOYD, OF BALTIMORE, MARYLAND.

BUCKLE.

SPECIFICATION forming part of Letters Patent No. 364,210, dated June 7,1887.

Application filed April 11, 1887.

To all whom it may concern.-

Be it known that I, JOHN S. BOYD, a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Buckles, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in bucklesto be used for various purposes, and espeeiall y to be usedin connectionwith my improved bag and inspection flap, application for which is madeof even date herewith.

As ordinarily constructed, buckles have been made so that the naturaltendency of the tongue is to close, or, having been closed, to It isfound in practice, however, that there often arises a necessity for abuckle which will normally tend to fly open, and which is only kept fromso doing by the pressure of the fabric with which the prong engages, andit is to meet this demand that I have invented the device hereinafterspecified and claimed.

In the accompanying drawings, forming a part of this specification, andon which similar letters of reference indicate the same or correspondingfeatures, Figure 1 represents a plan view of my improvement, showing thesame as it appears when not in use; and Fig. 2 isa eross-seetional viewtaken on the line a: 90 of Fig. 1.

The letter A designates a frame of the usual or any approvedconstruction, the same being preferably made of sheet metal, so that itcan be readily and easily stamped out, though it may be cast. The framein this instance is of rectangular form, though not necessarily so, andthe inner edge, B, of the forward bar, 0, is depressed, so that when thebuckle is in use and the teeth or prong is engaged the said prong willimpinge against the depressed edge B, and the points of the teeth, beingin a plane below that occupied by the surface of the frame, will nothurt or scratch any one who may be engaged in handling goods providedwith my'improved buckle.

The side bars, D, at a point somewhat forward of the rear bar, E, areprovided with inwardly-proj ecting supporting arms or lugs F, whichterminate in pivotal points. These Serial No. 234,878. (No model.)

arms may be cast separately and then soldered or otherwise secured tothe side bars, or they may be made integrally therewith, as in thepresent instance.

The letter G refers to the tongue, the same being, preferably, also madeof sheet metal and having one or more teeth or prongs, H, there beingthree shown. The rear edge, or that edge opposite the prongs, is bentover upon itself in such a manner-as to form hollow spindles I, intowhich the arms F project, and thus support the tongue.

The spring J, in the present instance a spiral spring, has the end Kbent toward the rear of the frame and under the tongue. The spring onthe other side is similarly constructed, so that the normal tendency ofthe springs is to force the tongue, not against the edge B, but awayfrom it, so that it is only the hold of the fabric upon the teeth thatkeeps the tongue held against the edge B.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a buckle, the combination, with the frame thereof, provided withbearings, of a tongue having arms mounted upon the bearings and a springmounted in proximity thereto in such manner as to normally keep thetongue away from its seat.

2. In a buckle, the combination, with the frame thereoflhaving itsforward bar depressed and the side bars provided with supportingarms, ofa tonguev having teeth and mounted upon said arms, and a spring arrangedin such relation to the tongue and arms as to normally keep the tongueaway from its seat.

3. As an improved article of manufacture, the herein-described buckle,the same consisting of a frame having the inner edge of its forward bardepressed and its side bars provided with supporting-arms, a tonguewhose spindles are mounted on the said arms, and a spiral springarranged with relation to the tongue and arms in such manner that thetongue will normally fly away from its seat- In testimony whereof Iaffix my signature in presence of two witnesses.

JOHN S. BOYD.
